the harry potter movies almost completely ruined the book series. i mean i understand that movies are going to differ from the book they come from, but come on... there is a line that should not be crossed if the movie is going to properly reflect the book (which i had assumed it was), not to mention the acting and the storyline in the movies were absolutely horrible until Year 3 (were it was promoted to just horrible)
so my vote is for Lord of the Rings, probably one of the best movie series i have ever see
